Question

11. Aminata bought 20 metres of cloth at a cost of $90. She sold 15 metres of cloth at $5.80 per metre and 5 metres at $3 per metre. (A) Calculate the profit she made. (B) calculate this profit as a percentage of her original cost.

Answer 1

Profit of 33 meters cloth :33(sp-cp)=11(sp):selling price of 11 meters cloth

=>3(sp-cp)=sp

=>sp=1.5*cp

profit %=((sp-cp)/cp)*100

profit =.5*100=50%

Let cost Price be x per meter.

Profit= 11x

S.p=C.p+profit

33x=c.p+11x

cp=22x;

Profit=11x/22x*100=50

HOPE IT HELPS!

Answer 2

Loss made by her = 15 × $5.80 + 5 × $3 = $102

Loss = $102 - $90 = $12

Loss percentage = (12/90) × 100

Loss percentage ≈ 13.33%
